About this app

This app helps you understand and precisely share what you feel daily and keeps track of what types of pain your treatments are helping.

You hurt. Your pain is chronic and complicated. You can’t remember everything. You want your doctors to understand, but you don’t know how to explain what you feel.

Nanolume® developed the Pain Tracker & Diary to help you record the daily textures, intensities, and locations of what you feel, so you and your care team can better understand what you are suffering with and follow how your pain responds to medications and treatments.

Pain is a complex experience. It often includes multiple pain types (layers), each with its own unique texture, intensity, location, and surface area.

By keeping a diary that integrates complex information, you can show your doctors what you are experiencing to help them make a better diagnosis, choose more appropriate medications and treatments, and monitor if your treatments are beneficial. In addition, by keeping such an integrated record, trends might emerge that would otherwise go unnoticed.

Pain is a subjective (not objective) sensation that you cannot measure. Its assessment relies on each person’s ability to communicate what they feel. Nanolume® developed this digital diary to help you record what you feel every day.

For each diary entry you create:
• Choose a Pain Type. Choose from a list of predefined pain types or create a customized pain type. Next, tap the icon of the pain type you feel is most intense (you can come back and add more types later).
• Select the Intensity. Select the intensity of your pain type using a Numeric Rating Scale (NRS).
• Draw an Outline. Use your finger to draw an “outline” of the type of pain you are experiencing on the front and back sides of a generalized map of your body.
• Calculated Surface Areas. The app displays the percent [%] of your body surface affected by each (or all) of the pain types you draw.
• Zoom. Need to see a larger image of your hand or foot? Double-tap: once to zoom x2; twice to zoom x4; a third time to restore the original size.
• Notes. Tap the “Notepad” icon located in the top-left corner of each opened diary entry to record any details of your medications or treatment results.
• Tap "Add Pain." Choose another pain type (layer) to draw.
• Save Your Diary Entry. Tap "Done" to create a snapshot of all the pain type layers you drew. The app attaches the date and time your entry was saved.
• Open a Saved Entry. Tap on the date and time of the entry you want to review. Look at the intensity, location, and surface area of each pain type you experienced (by touching the icon of the pain type you want to see) or see all the pain types at once and see how they overlap (tap the "All Layers" icon). Swipe the picture left or right to check how your other pain entries compare over time.
• Charts. View a summary of your data in "Charts."
• Forget to Save an Entry? Go back and recreate a "pain picture" from the past; then, use the "Calendar" icon to backdate the recreated entry.
• Calendar Backdating. Touch the "Calendar" icon to backdate any pain-picture you draw to create a record of what you remember from the past.
• Copy/Edit. Copy or edit a copy of a previous entry.
• CSV Export. Email or save a numeric file of your data, then open that data in a spreadsheet.
• Interactive Summary & Animation. Play an animation of your data to see how your pain types change within any period you choose by selecting the corresponding start/stop dates.
• PDF Export. Export your charts, drawings, and notes as a PDF file.

It is okay, but not great. I would like to scroll in for better control on drawing and maybe have patterns that are not so far apart or even have them solid colors. I would also like to drop a pit on the body map and make note with pins/dots or even notes for the colors. I also would like it if there was an option to input medications and when you took them. It works okay, but I just expected better features. Feels one step above elementary. Which isn't bad. Just not great.

For “better control” to outline smaller areas try our zoom feature to magnify the image. We offer only two solid colors because overlapping solids are difficult to see through. Users can make the size of the patterns smaller. We offer over 10 features. What features would you like to see? We’re exploring adding meds. Pls contact us for more info.

This app has been very helpful tracking symptoms after an accident, because while I can generally remember what has hurt most consistently, I certainly don't remember every detail unless I make a record of it. And when I had a problem with the app, the administrator communicated quickly & often until we figured out what I was doing wrong. I definitely recommend this app.

UPDATE: I've had to change my review due to the changes in the privacy policy. This app no longer protects your privacy as it should, don't know why. I'm soft locked because I don't agree with the policy. It used to be a private useful app. I did recommend it for people with chronic pain. It helped me keep track of my pain cycle and pinpoint the areas that are problematic or that are improving. I do wish I could add more to it though, a more robust diary would be nice or a space for medication.

Hello. Pain diary data is private. It has been that way and remains that way unless you choose to share it. That policy has not changed. Would you please let us know your concerns or why you think our Privacy Policy changed? If questions, please contact: Thanks.

What's new

This version increases the precision of the average pain intensity as it is displayed on diagrams, the entry list, charts, and when exported. It also increases the displayed precision of coverage percentages and improves the legibility of the entry statistics on the home screen.
